Overview of the 7-BM Beamline

The 7-BM beamline is dedicated to time-resolved measurements of complex fluid flowfields using x-ray radiography and fluorescence spectroscopy. Funding for the final commissioning of 7-BM was provided by the DOE Office of Energy Efficiency and Renewable Energy. Commissioning was completed at the end of FY2012. The beamline is currently operated by the X-Ray Science Division of the APS.

Major Areas of Research

Fuel sprays from automotive fuel injectors, both diesel and gasoline. See more on the X-Ray Fuel Spray web page from Argonne's Energy Systems Division.

Sprays for air-breathing propulsion.

Fuel injection for rocket injectors.

Gas-phase fuel injection, mixing, and combustion.

Status of 7-BM

The X-Ray Fuel Spray group in Argonne's Energy Systems division has recently set up a YouTube channel with research highlights, many of which come from research done at 7-BM.
